WHAT DO THESE WORDS MEAN?

Terms and Definitions:

Bait:

It is substance placed strategically so that the Pest may approach it and eat it considering a food source and end up being poisoned. Baits are made to be palatable to the Pest and formulated to last longer than normal fresh foods.

Most baits are NOT instantly lethal to the target Pests. The advantage is that the bait may be taken to the Pest population that may not leave the nest and that the Pest would like die off in the nest and not in our living spaces.

Since most baits are formulated such that they do not cause any immediate discomfort to the Pest; the Pest is likely to have multiple feedings and encourage other members to feed as well.

Examples: There are baits in GEL or PASTE formulations to target ants and cockroaches whereas to target mice, the bait formulation is Block.

Dust:

Insecticide is formulated in a powder form. The actual amount of insecticide is much less and the carrier powder is the bulk of it. This powder is usually applied using a a device called the duster.

Like the spray, the dust is usually applied in cracks, crevices, gaps and voids where the Pest may live and/or forage.

Examples: The ZP Powder is dusted where mice may travel (but where no human contact occurs). This powder gets into their feet and later poisons them when they groom themselves.

Fogging or Fumigation:

This technique of Pest Control requires a gas like application of the insecticide to a contained area of a structure for certain duration of time to deliver an effective deadly impact to the targeted pest. The insecticide substance is dissolved in a substance called Fumigant. This mixture is used in a device called Fogger. Fogger either heats up and ionizes the fumigant or mixes the fumigant with ambient air and pushes out a fast stream in the targeted environment. What comes out of the Fogger is a stream of very small particles of insecticide that appears as smoke or fog.
The Fog is targeted towards the areas and surfaces to be treated. Because this insecticide form remains suspended in the environment for long period, it reaches and lands on almost all surfaces and areas. The residual insecticide value of this treatment is not as good as in the Spray method.
Examples: It is suitable for exterminating House Flies indoors and for other flying insects outdoors in the bushes.

Spray:

The insecticide may come in powder or liquid form. It is dissolved in a carrier liquid (usually water) and shaken under pressure in a sprayer. It is usually sprayed on the surfaces and inside the cracks and gaps where the pest may live and/or forage.

The Pest gets affected by contacting these surfaces and gets poisoned. Insecticide Spray may have different degree and swiftness of affect on different Pests. Usually an insecticide that kills very fast does not stay affective for very long.
Examples: Spray application to the bed components for a Bed Bug infestation.

Trapping:

Trapping is the extermination technique for Rodents and Insect Pests where they get immobilized by becoming stuck and/or killed by the entrapping apparatus. The traps may utilize glue, instant door close or some means of snapping or zapping the pest.
